Old Synopsis: A way to make g++ crash (segfault)
New Synopsis: SegFault with local undefined types and templates
State-Changed-From-To: open->analyzed
State-Changed-By: bangerth
State-Changed-When: Tue Dec 10 14:14:09 2002
State-Changed-Why:
Confirmed. Here's a testcase that is smaller by about a
factor 4000:
--------------------------
template <class T> struct Base {
struct Local;
};
template <class T> struct Derived: public Base<T> {
void g(struct Local) {}
};
template class Derived<int>;
------------------------------
This ICEs with all versions since at least 2.95. Presently
I get
g/server> /home/bangerth/bin/gcc-3.2.2-pre/bin/c++ -c main.ii
main.ii:6: warning: `struct Local' declares a new type at namespace scope
main.ii:6: warning: names from dependent base classes are not visible to
unqualified name lookup - to refer to the inherited type, say `struct
Derived::Local'
main.ii:6: internal error: Speicherzugriffsfehler
